When a truck crashed into WMAR-TV, dozens of employees fled. One remained behind, feeding information to police.

Nic Hall has worked for the Baltimore-area ABC affiliate, owned by E.W. Scripps Co., for two weeks. In an interview Tuesday on the station's evening newscast, he said a co-worker left to make copies but never came back. Then he heard from another employee, working off-site, who asked why he was still in the office. That's when he learned a man rammed the truck into the lobby.

Hall connected with Baltimore County police and was on the phone for the next 3 1/2 hours "letting them know the lay of the land." He's a reserve Marine, and talked with a fellow Marine among the responding officers. A SWAT team walked him outside to safety.
